# We initially noticed that, sometimes, "dhclient -6" disappeared.
# To fix that, we put 'dhclient -6' under sv.
#
# Now, with 'dhclient -6' always there, if the interface link status
# flaps, the 'dhclient -6' process started before the interface was up
# does not do DHCPv6 request anymore.
#
# The approach here is to restart 'dhclient -6' when the interface is up.
sv restart dhc6
